"What people are saying"? So instead of understanding and solving some
issue you just jump wagon, maybe only to find some other issue there?
ext4 is stable and works perfectly. You just have to configure it
properly, as with anything.
Can you still recreate the filesystems? If so, study the parameters for
ext4 and use them. You will want "extents", because it provides a much
better use of disk space and avoids fragmentation.
As you are, you can still create a journal on the filesystem you have,
using tune4fs. Look under switch -o (options).
As an example, I give you some of what I have here with a ext4 partition:
LABEL=/data1 /data ext4
defaults,data=journal,acl,user_xattr 1 2
tune2fs gives me the following:
Filesystem features: has_journal ext_attr resize_inode dir_index
filetype needs_recovery extent flex_bg sparse_super large_file huge_file
uninit_bg dir_nlink extra_isize
Filesystem flags: signed_directory_hash
Default mount options: journal_data user_xattr acl
